1 AC125 PNP Germanium transistor, new old stock, made by Tungsram. They are a direct substitute for OC81d and work great in fuzz pedals. Gain range is 60-130, so they are right in the fuzz face range. My Philips AC125's are higher gain if that's what you need. These are untested and sold as/is, but if you need a matched pair or even just one piece tested, I can do that for $3 per transistor. You will need to buy one of item 'GE transistor testing fee' in the germanium transistor category for each transistor you want tested. For matched pairs, you will also need to email me with the gains you want.

This is the fee to have germanium transistors tested for gain and leakage.
